After purchase, and after I online. About This Mac show 11-inch, Mid 2011.

I am very sure the info here is incorrect because this is a 13-inch. The serial Number is also false. even the processor turns out to be inaccurate. I have opened up the macbook air myself and I am sure of it.

I don't really mind all that now. But I want to correct the info on About This Mac. I've clean format the mac using external thumb drive, but all the info is still inaccurate. can anyone teach me how to correct it?

I know how to change the About This Mac by editing AboutThisMac.strings but this is not what i want to achieve as it is not real. Can anyone help me to reset the Info back to its REAL Info?

If the spec is OK, it may have just had the wrong serial number put in during a repair. It can happen.

The spec is not right. This macbook air is actually a 1.7GHz i5. not 1.8ghz i7. I did consider the serial number scenario as you suspected but I am not sure if that will effect the information on the following information

It uses the serial number to determine which model to show. The last 3 digits of that serial will be of an 11" air - hence why it thinks it's an 11". That can happen during repair, and there's nothing to worry about. As for the specs - no idea why they're incorrect - are you *sure* you have an i5 - how did you check?
